Specification of Letters Patent. A

Patented March 10, 1908.

To all whom it may concern:

Be it known that 1, ROBERT M. DixoN, a citizen of the United States, residing at East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Beacons, Light- Buoys, &c., of which the following is a specification.

My invention relates primarily to beacons, light buoys, etc., but may be applied in other situations.

The principal object of the invention is to provide means whereby a lens or other light variant may be moved or rotated by the flow of fluid, for instance, compressed air, gas or water or the flow of gas to a burner.

My invention will be described generally with the aid of the accompanying drawing in which I haveshown merely by way of lllllS- tration in sectional elevation one form of an apparatus in which my invention is embodied.

In this drawing: a indicates a suitable burner and b a lens surrounding the same the chimney a being provided to carry out the roducts of combustion. The burner and ensare suitably sup orted as, for instance, upon a platform d, w ich platform is or may be provided peripherally with a suitable driving gear e, herein shown as a bevel-gear. The lens and burner are in the present in stance carried centrally above a suitable pillar f andthe platform is sup )orted by a suitable float g resting in an annu ar mercury well It so as to permit the float to rotate freely therein. The mercury well is preferably adjustable up and down by means of an adjustable collar L which is threaded upon the outer peripheral surface j of the pillar f. The pillar f may be'suitably supported, as by means of a suitable base or stand 76.

Mounted upon the base or stand 70 is a standard Zwhich is herein shown as supporting a shaft 0 on which is mounted a pinion p meshing with the bevel-gear e. Asuitable motor m is provided for driving the shaft 0,

the rotating part of the motor q being shown in dotted lines as meshing with the pinion 1*; also shown in dotted lines as mounted on the shaft 0. Motor m is a fluid pressure motor and is adapted to be rotated or moved by the movement of gas, air or other fluid therethrough. The pipe 8 may come from a suitable source of supply, for instance, a tank t, as roughly indicated on the drawing, and the fluid passes into and through the. motor. In the illustrative drawing it is shown as passing by pipe u to the lower part of the standard 7, passing upward throu h the standard by a pipe 1) to the burner a t irougha chamber w.

The operation of the device will be obvious from the drawing and description. The

fluid passing through the burner rotates the motor, which, in turn, rotates the pinion 2), thereby rotating the gear 6 which carries the lens I). A flashlight or signal is thus obtained and although the device is most conveniently used as a beacon it may, however, be applied in other situations where a flash light or signal is desirable, it being understood that the motive fluid, arrangement and construction of the parts and light variant apparatus may be varied without departing from the spirit of my invention;

Having described my invention, what I claim and desire to secure by Letters Patent 1. A lamp, a lens, a float therefor, a tank, a mercury bath therein, means for adjustably elevating said tank, and a rotator for said float.

2. A float, a lamp and a lens carried thereby, a tank adapted to contain a mercury bath, a cock for draining portions of mercury from said tank, an adjustable elevator for said tank, and an automatic rotator for said float.

ROBERT M. DIXON.
